The method includes receiving payment device data from an electronic payment device of a user during a payment transaction between the user and a merchant. The method also includes receiving at least one script for execution on the POS terminal from the electronic payment device. The at least one script is associated with a digital signature. The method further includes verifying the at least one script based on the digital signature of the at least one script and executing the at least one script on the POS terminal to cause an action associated with a user interaction with the POS terminal to be performed.

BACKGROUND 1. Technical Field

Disclosed embodiments or aspects relate generally to computer user interfaces and, in one particular embodiment or aspect, to a system, method, and computer program product for customizing point-of-sale (“POS”) terminal functionality for user interfaces and related to user interactions.

2. Technical Considerations

Traditionally, the customization of POS terminals (e.g., computing devices configured to interface with payment devices to complete transactions between users and merchants) is an inefficient and laborious task. For example, POS terminals may allow for customization of displayed text in a language of a card user's preference. However, to add support for the display of text in a new language, all POS terminals in a region must have their software updated, since a user may visit any one of the POS terminals in the region to complete a transaction. Similarly, if a banking institution wants to integrate a rewards program for users when they are checking out, then the programmed functionality must be pre-established for all POS terminals in the region for the program to be fully operable. As such, there are massive inefficiencies involved with changing or customizing POS terminal functionality (e.g., payment processes, rewards processes, text size and style, sound settings, types of personal information collection, custom advertisements, security settings, and/or the like).

Moreover, there may be many different varieties of POS terminals deployed in a region, where different POS terminal suppliers are in control of their own POS terminal interfaces and processes that users encounter. A user is unlikely to encounter the same customized functionality for each POS terminal unless each and every POS terminal supplier updates their POS terminals accordingly. In this manner, there are massive technical obstacles to full user customization of POS terminal functionality.

Therefore, there is a need in the art for a technical solution to provide for customizing functions of POS terminals without the requirement of POS terminals being updated or pre-programmed altogether.

Non-limiting embodiments or aspects of the present disclosure are directed to a system, method, and computer program product for customizing functions of a point-of-sale (POS) terminal. Described embodiments and aspects improve upon prior art technical solutions by removing the need for pre-programmed software updates to be pushed to all POS terminals in a given region of operation. By the embodiments and aspects of the technical solutions described herein, the functionality of POS terminals can be customized (e.g., visually, aurally, procedurally, etc.) at the time of user interaction (e.g., pressing a button, touching a screen, viewing an image, reading a message, hearing a sound, and/or the like) via scripts stored on and communicated from payment device of a user. Moreover, existing payment device authentication and transaction processes can be augmented by script validation and execution processes, whereby POS terminals can verify the authenticity and/or the security of scripts, determine whether scripts are executable on the current POS terminal, and execute the custom POS terminal functions at run-time. Accordingly, the variety and range of customized functionality and user interfaces is greatly improved, the software upkeep for POS terminals is reduced, and the speed in which custom functions are loaded/executed may be increased by initiating the customization during the initial data exchange between a payment device and the POS terminal. These improvements, among others, are detailed by the further disclosure below.

With specific reference to FIG. 1, and in non-limiting embodiments or aspects, provided is a system 100 for customizing functions of a point-of-sale (POS) terminal. The system 100 includes a POS terminal 102 that may include a display 104 (e.g., a screen), a speaker 106, and at least one processor 108. The POS terminal 102 may be associated with a merchant and communicate with a payment device 110 (e.g., an electronic payment device) of a user 112 to complete a transaction between the user 112 and the merchant. The payment device 110 may store payment device data 114, including, but not limited to, an account identifier, an account token, an account holder name, a payment device type, and/or the like. The payment device 110 may also store at least one script 116 (e.g., a set of computer-readable instructions for execution by one or more processors) that is configured to customize an existing function of the POS terminal 102 or cause the execution of a custom POS terminal 102 function. For example, existing POS terminal functions that may be customized may include, but are not limited to, the display of a total price, the playing of sound to represent transaction status, the form of acceptable functional input, the display of a cashback interface, the display of transaction processing status, etc. For the example of the display of a total price, said existing function may be customized by changing the size/style of the font text, by sounding the price aloud via a speaker 106, by displaying the text in a different language, by displaying the price in a different currency, by displaying the amount of tax separately, and/or the like.

Custom POS terminal functions may include, but are not limited to, the display of a payment-device related rewards interface (e.g., to show points earned, to allow for point redemption, etc.), the playing of an audio sequence such as a tune to signify transaction completion, the display of an interface to allow a user to select how payments will be made (e.g., single payment, multiple payments, etc.), and/or the like. In view of these non-limiting examples, it will be appreciated that scripts 116 may provide for customized POS terminal functions through any combination of displaying at least one message, displaying at least one image, displaying at least one animation or at least one video, playing at least one audio sequence, displaying a user interface comprising at least one user option for selection, displaying at least one user data input field, communicating data to a third party server, receiving data from a third party server, and/or the like.

With further reference to FIG. 1, and in further non-limiting embodiments or aspects, the payment device 110 may store one or more digital signatures 117 corresponding to the one or more scripts 116. A digital signature 117 (e.g., a one-way hash encryption of a script 116, passcodes, asymmetric cryptographic keys, and/or the like) may serve to authenticate the user 112, a script 116, and/or the like. The payment device 110 may further store a set of stored script identifiers 118, which may identify one or more types of scripts 116 that the payment device 110 is storing/capable of transmitting. A script 116 type may be with regard to type of display/audio settings, third party communications, programming language, issuer institution program, script size, and/or the like. The POS terminal 102 may be likewise programmed and/or configured to store a set of executable script identifiers 120, which may identify one or more types of scripts 116 that the POS terminal 102 is capable of executing. A “set,” as used herein, may contain zero or more elements (so as to include a null or empty set).

The POS terminal 102 may receive from the payment device 110 a set of stored script identifiers 118 and compare the set of stored script identifiers 118 to the set of executable script identifiers 120 to determine a set of script identifiers that are common to both sets. The POS terminal 102 may communicate the common script identifiers, if any, to the payment device 110, in response to which the payment device 110 may communicate to the POS terminal 102 the scripts 116 corresponding to the common script identifiers. Alternatively, the POS terminal 102 may receive all of the scripts 116 from the payment device 110 but use the comparison of the set of stored script identifiers 118 and the executable script identifiers 120 to determine which scripts 116 to run.

With further reference to FIG. 1, and in further non-limiting embodiments or aspects, the system 100 may include a transaction service provider system 122 communicatively connected to the POS terminal 102. The POS terminal 102 may communicate transaction authorization requests to the transaction service provider system 122 to complete a transaction between the payment device 110 and the POS terminal 102. If an executed script 116 received from the payment device 110 includes instructions related to the completion of a transaction, script-related payment data may be embedded in the transaction authorization request. For example, if the script 116 causes the display of a payment method option screen for selection by the user (e.g., single payment, multiple payments, multiple accounts, etc.), data of the user's selection may be embedded in the transaction authorization request and acted on by the transaction service provider system 122, an issuer institution server, and/or the like.

The system 100 may further include a third party server 124 communicatively connected to the POS terminal 102, such as by a distributed data network connection (e.g., an internet connection). An executed script 116 received from the payment device 110 that includes instructions related to sending and/or receiving data from the third party server 124 may cause the POS terminal 102 to communicate with the third party server 124 accordingly. For example, the script 116 may include instructions to communicate an identifier of the user 112 to the third party server 124 and to receive back data related to a rewards or incentive program associated with the payment device 110, further causing the POS terminal 102 to display a rewards redemption/status interface to the user 112. The user's 112 selection may then be communicated back to the third party server 124. Third party data may also include the promotion of products or services from merchants or issuers (e.g., an advertisement to make a purchase), notifications of credit limit use (e.g., “You have used 95% of your credit limit”), and/or other like communications.

With further reference to FIG. 1, and in further non-limiting embodiments or aspects, the script 116 may be configured to cause a message to be displayed on a display 104 of the POS terminal 102. For example, the script 116 may include: “<script> <display> veuillez retirer la carte </display> <signature> 0EF5DA34 </signature> </script>.” Such a script 116 may be communicated to the POS terminal 102 after all the payment device data 114 is communicated from the payment device 110. This example script 116 includes an embedded digital signature 117 and is in markup language, but it will be appreciated that many arrangements, combinations, and types of computer instruction languages may be used, including, but not limited to, compiled languages (e.g., C, C++, C#, Python, Haskell, etc.), concurrent languages (e.g., Java, Ada, E, etc.), declarative languages (e.g., SQL, Mercury, etc.), embeddable languages (e.g., PHP, JavaScript, etc.), and/or the like. After verifying the “<signature>” element of the script, the POS terminal 102 displays “veuillez retirer la carte” on the screen, which is a French translation of “please remove card.” In this manner, one or more functions of the POS terminal 102 are customized, without the POS terminal 102 being programmed to communicate in French or to pre-determine what kind of text is to be displayed in French for a given user interaction.

With further reference to FIG. 1, and in further non-limiting embodiments or aspects, the script 116 may be configured to trigger a cashback feature associated with the issuer institution of the payment device 110. For example, the script 116 may include a call to a third party server 124 within a message: “<script> <display> You get <get> https://bank.com/cardscriptservice/cashbackamount/DA287712</get> cashback in this transaction! </display> <signature> 0EF5DA34</signature> </script>”. After verifying the digital signature 117 of the script 116 (in the “<signature>” tag), which is embedded in the URL of the script 116, the POS terminal 102 may communicate with a third party server 124 (e.g., a remote endpoint) to transmit an identifier of the user 112 (e.g., “DA287712,” embedded in the URL″). The third party server 124 may then communicate back a response based on the user 112 identifier, e.g., a cashback reward corresponding to the transaction, such as $2.32. Therefore, the POS terminal 102 would display a message of “You get $2.32 cashback in this transaction!” on the display 104.

With further reference to FIG. 1, and in further non-limiting embodiments or aspects, the script 116 may be configured to trigger a custom POS terminal function to allow a user to select a payment method, such as by installment payments via the issuer institution of the payment device 110. For example, the script 116 may include: “<script> <menu> <target> card </target> <menu_header> How do you want to pay? </menu_header> <menu_item> <id> 1 </id> <menu_text> Full amount </menu_text> <menu_item> <id>2 </id> <menu_text>3 months installments </menu_text> </menu_item> </menu> <signature> 0EF5DA34</signature> </script>”. After verifying the digital signature 117 of script 116 (e.g., embedded in the “<signature>” tag of the script 116), the POS terminal 102 may display a menu on the screen:

TABLE 1 How do you want to pay? 1. Full amount 2. 3 Months installments

After the user 112 selects an option, e.g., option (2), using an input of the POS terminal 102 (e.g., a keypad, a touch screen, etc.), the POS terminal 102 may embed the selection in a transaction authorization request, or it may communicate the selection to the payment device 110 for the payment device 110 to embed the payment type into the payment data to be communicated to the POS terminal 102. After completing the foregoing script 116, the transaction would be completed according to the user's 112 selection.

With specific reference to FIG. 2, and in non-limiting embodiments or aspects, provided is a method 200 for customizing functions of a POS terminal. The method 200 may be performed by one or more processors of the POS terminal, and one or more of the steps therein may be performed by processors communicatively connected to the POS terminal, such as a checkout computer terminal, a vendor server, a network modem, and/or the like. In step 202, payment device data is received based on the POS terminal from a payment device of a user during a transaction, such as a payment transaction, between the user and a merchant. The payment transaction may include any and all steps from when a user decides to engage in an exchange with a merchant until the exchange is completed. The payment device data may include a payment device identifier, such as a credit card number, which may be encrypted.

The method 200 may further include a script check process 300, as further shown in FIG. 3. In step 204, one or more scripts are received from the payment device for execution on the POS terminal. The scripts may be associated with digital signatures to authenticate/verify one or more of the following parameters of the script: the contents of the script, the script type, the payment device, the user, or any combination thereof.

In step 206, the script may be verified by the POS terminal at least partially based on the digital signature associated with the script. For example, the POS terminal may use a public key of a cryptographic digital signature to verify the script. In step 208, the script may be executed on the POS terminal to cause one or more actions associated with a user interaction with the POS terminal. User interactions for which POS terminal functions may be customized include, but are not limited to, inputting personal user data, inputting information for a payment process, viewing status of payment, viewing and interacting with advertisements, viewing and interacting with offers/rewards, selecting payment options, selecting receipt options, reading messages, observing visual/audio feedback from the POS terminal, and/or the like.

Non-limiting embodiments or aspects of such actions are further described in connection with FIG. 4 via an illustrative script execution process 400. Ultimately, the POS terminal may perform a transaction authorization process, in step 210, to complete the transaction between the user and the merchant. Step 210 may include generating and communicating, by the POS terminal, a transaction authorization request to a transaction service provider system, which may include payment device data (e.g., a payment device identifier), and which may include additional data derived from the script-initiated actions (e.g., user input).

With specific reference to FIG. 3, and in non-limiting embodiments or aspects, the method of customizing functions of a POS terminal may include a script check process 300. The script check process 300 may be performed by one or more processors of the POS terminal, and one or more of the steps therein may be performed by processors communicatively connected to the POS terminal, such as a checkout computer terminal, a vendor server, a network modem, and/or the like. The script check process 300 may include, at step 302, receiving, with the POS terminal, a first set of identifiers of scripts associated with one or more types of scripts that a payment device (e.g., an electronic payment device) is configured to transmit. For example, the payment device may have three scripts stored thereon, related to a type of audio sequence action (e.g., playing a foreign language audio message), a type of third party-data action (e.g., initiating a cashback process interface), and a type of display action (e.g., displaying an advertisement). The payment device may communicate three identifiers to the POS terminal corresponding to the three types of scripts it is configured to transmit.

In step 304, the first set of identifiers may be compared by the POS terminal to a second set of identifiers of scripts associated with one or more types of scripts that the POS terminal is configured to execute. For example, the POS terminal may be equipped with a screen and a data connection to a third party server, and therefore it may have a set of script identifiers associated with display actions, third-party data actions, and/or the like. However, if the POS terminal does not have a speaker, it may not be able to play audio sequences, and therefore the second set of script identifiers would not include such an audio-related script identifier. In step 306, a set of common script identifiers, corresponding to script identifiers common to both the first set and second set, may be determined and communicated to the payment device, so that scripts relating to the common script identifiers may be communicated to the POS terminal for execution. It will be appreciated that script identifiers may also relate to other parameters besides general categories of script types including, but not limited to, script languages, script authors, script size, unique script ID, and/or the like.

With specific reference to FIG. 4, and in non-limiting embodiments or aspects, the method of customizing functions of a POS terminal may include a script execution process 400. The script execution process 400 may be performed by one or more processors of the POS terminal, and one or more of the steps therein may be performed by processors communicatively connected to the POS terminal, such as a checkout computer terminal, a vendor server, a network modem, and/or the like. In step 402, the POS terminal may cause, in response to executing one or more scripts, an action associated with a user interaction with the POS terminal to be performed. In non-limiting embodiments or aspects, the action may include one or more customized functions (e.g., POS terminal actions) to be carried out. Script-initiated functionality may include, but is not limited to, displaying a message (step 404), displaying an image (step 406), displaying an animation or video (step 408), playing an audio sequence (step 410), displaying a user interface with options for user selection (step 412), displaying a data input field for user input (step 414), communicating data to/from a third party server (step 416), or any combination thereof. Any given script-initiated functionality may include one or more of the foregoing steps.

Step 404 may include, for example, displaying at least one message on the POS terminal including an instruction for completing the payment transaction, such as “Press ‘OK’ to confirm amount,” “Enter PIN,” “Submit payment,” and/or the like. The message of step 404 may be in a language specified by a script that is the same or different from the default language of the POS terminal. For example, the POS terminal may be programmed and/or configured to display messages in English, but the script, when executed, may display messages in another language, e.g., French. Because the system does not require the POS terminal to be pre-programmed with script operations, the script can customize messages to be displayed in any necessary format, style, size, or language.

Step 414 may include, for example, displaying a user interface on the POS terminal including at least two options for selection (e.g., control buttons, touchscreen icons, etc.) including a first user option to complete the payment transaction in a single payment and a second user option to complete the payment transaction in multiple payments. Additional options or messages may be provided to specify the type of multiple payments (e.g., two payments over two months, four payments every quarter year with interest, etc.). The POS terminal may then modify a transaction authorization process, as in step 210 of FIG. 2, particularly as initiated by the script, to communicate a transaction authorization request having data associated with the user selection of the first user option or the second user option. For example, if the user selects a multiple payments option, such as two payments over two months, data regarding that selection may be embedded in the transaction authorization request, which may be used by an issuer institution to control the use of funds of the user's account.

Step 416 may include, for example, communicating transaction data and/or payment device data, including a payment device identifier, from the POS terminal to a third party server. The third party server may use the transaction data and payment device data to update spending records (e.g., for rewards programs, offer programs, fraud analysis, market analysis, or other spend-tracking services). The third party server may then generate data for communication back to the POS terminal, which may then be provided to the user interacting with the POS terminal. For example, the third party server may receive the transaction data and payment device data for a rewards program associated with the user and/or the payment device. For a rewards program where the user earns $1 cashback for every $100 spent, and for a transaction where the user is making a $52 purchase, the third party server may determine that the user has earned a $0.52 cashback reward. The third party server may then transmit transaction rewards data to the POS terminal for presentation to the user. Transaction rewards data may include cashback, discounts, third party partial payment, electronic badges/achievements, gift redemptions, and/or the like. The user may then interact with the POS terminal, if required, to choose a reward, check a reward status, delay receiving a reward, and/or the like. For the above illustration, the user may choose to redeem the $0.52 reward or save the $0.52 reward to continuing building up their reward earnings.
